Communication is critical at sea. Here, a crew member from the U.S. Coast Guard iceabreaker Healy signals a winch operator to stop lowering at CTD (conductivity, temperature, depth) rosette to the deck. During research cruises, delicate (and often heavy) scientific instruments can become hazardous, swinging pendulums that demand a well-oiled ship's crew to ensure the safety of everyone on board. During this particular cruise, WHOI biologist Carin Ashjian led the first winter cruise into the harsh and unforgiving Arctic to study the biology of the Bering, Chukchi, and Beaufort Seas.
